How does redundancy benefit network architecture?

Redundancy plays a crucial role in enhancing the reliability and availability of network architecture. By incorporating redundancy, you ensure that critical components—such as routers, switches, or links—have backup systems in place. In the event of a failure, these backups can take over seamlessly, allowing the network to continue functioning without downtime. This is particularly important for organizations that rely heavily on their network for daily operations, as any disruption can lead to significant losses in productivity, revenue, and reputation.

While redundancy may have indirect impacts on cost savings or the ability to support more users due to improved reliability, the primary and most immediate benefit is the assurance that critical functions remain operational when failures occur. This resilience is essential for maintaining service level agreements (SLAs) and ensuring continuous access to services and applications.
